Fibonacci Numbers and the Golden Section

(www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/fib.html)

Age Range: 10-18 (Grades 4-12 approximately, with parental supervision)

 

In the 13th century, Leonardo Fibonacci discovered a progression of numbers in which each number is the sum of the two preceding numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, etc. These numbers recur in patterns in nature – such as in the pine cone and in seashell patterns. The creator of this site, Dr. Ron Knott, provides many activities for discovering Fibonacci numbers along with clear explanations and excellent diagrams and pictures.


When you get to the site, you’ll see a lot of text. Don’t let that deter you. It clearly explains the easiest way to explore the contents. 

Our suggestion is to start by listening to Dr. Knott’s interview on BBC radio about Fibonacci Numbers (45 minutes). You can listen online or download the podcast. It is a useful general introduction to Fibonacci Numbers and the Golden Section (which you’ll learn more about at the website too). 

After listening to the interview, head over to the introductory page that reveals Fibonacci numbers in nature. It includes fun activities that really help students see patterns in nature. Then try the puzzles, mathematical explorations, and learn about applications of Fibonacci numbers.

The site also provides excellent explanations and activities about the Golden Section and Golden String that also appear in nature. The content is geared for about 5th grade and up – but younger children may enjoy seeing how math exists in nature too. It’s a great way to show kids that math is all around us!

 The National Council of Teachers of Mathematics offers this website that is designed to help families enjoy math OUTSIDE OF SCHOOL through a series of fun and engaging, high-quality challenges that improve problem solving skills. The challenge activities that are designed with middle school math in mind, can be done online or downloaded in pdf files to print and use offline.

When you get to the site you will see animated characters and the words “Take A Challenge.” Click on those words and go directly to 4 math challenge problems that include: 

  • Line Up – How long would you have to wait if you were number 300?
  • Beating Heart – How fast does your heart beat?
  • Popcorn – Which shape holds the most?
  • Don’t Fall In – Why are most manhole covers round?

If you decide to take the challenge, notice that each time you click on a different math challenge, the menu bar at the top of the page will change allowing you to access hints and tips that will help solve the problem. If you like these challenges then go to the “Challenge Index” on the menu where you can access 80 challenge problems archived at the site.
 
Before you begin the challenges, you might want to take a moment or two to view the menu items on the home page. It includes information for teachers and for families in English and in Spanish along with a “Math Index.” The Math Index lists all of the challenges archived at the site by math topic such as algebra, geometry, measurement, numbers, statistics and probability – allowing you to more easily access the activities that relate to the strand of math you want to study.
 
Each of the challenge activities are designed to capture students’ attention with real-life problems making the math much more meaningful and thought-provoking. Families can have fun solving the challenge questions together. Bookmark this page, so you can return to the site and explore them all.

Age Range: 11-18 (Grades 5-12, with parental supervision)

 

This website offers a free archive containing hundreds of math problems and puzzles for a variety of skill levels.

When you get to the site you’ll see a horizontal menu near the top of the page. Click on “Problems” to access the archives. You can search by keyword for specific math strands such as algebra, geometry, trigonometry, calculus, etc.
 
You can also search by level of difficulty. The problems are ranked with stars and explained as follows: 

  • One Star – These problems require nothing more than a logical mind and a willingness to try things out on paper.
  • Two Stars – Problems begin to require insights and mathematical tools. For example, geometrical problems may require the use of simple trigonometry, number problems may require knowledge of factoring, etc.
  • Three Stars – A good knowledge of school mathematics and/or some aspects of proof will be required.
  • Four Stars – A comprehensive knowledge of school mathematics and advanced mathematical tools will be required.

Each word problem or puzzle comes with an illustrated solution, and often has suggestions for further exploration and learning.

Tunes That Teach Language Arts & More!

The Music Room

(www.suzyred.com/music.html)

Age Range: All (All grades; children with parental supervision)

 

Rote memorization of grammar and spelling rules can be boring and ineffective. When you set rules to music – they are easier to remember.

That’s the premise of this site that provides songs that teach language arts rules such as: 

  • Contractions
  • Synonyms & Antonyms
  • Homonyms
  • Persuasive Writing
  • Vowel Rules
  • Adverbs
  • Nouns, Adjectives, & Verbs
  • Spelling Rules
  • Vocabulary
  • and much more

When you get to the site you’ll see a menu of Language Arts songs – just click on the topic of interest to you and a new page opens displaying the lyrics to the song that is set to familiar music. In most cases, you will hear an audio clip of the music as well. Not only that, some of the titles link to other sites with fun music videos.

When you’re through learning about Language Arts, check out the rest of the menu to find songs that help kids learn Math, Science, and Social Studies. There are even “Just for Fun Songs” that include links to other sites with popular children’s music.

In some instances on the site, you will find information about how to purchase some of the music on CD. There is no obligation to purchase to hear most of the musical lessons provided on the site.

Geometry “Eyeballing” Game

Age Range: 10 and up (Grades 5 and up, approximately; children with parental supervision)

 

Are you one of those people who needs to straighten slightly crooked pictures on the wall, when others aren’t even aware that something is just a little off square, off center, or not quite straight?


Then you’ll love this website that provides a free game that allows you to test your ability to determine if things are straight or crooked, while improving your spatial relativity and visual geometry skills.

When you get to the site you will see the game screen displayed. Click on “Help/About” below the screen, to get information on how the game works. You’ll have one chance in each of the following 7 categories to get the shapes as close as you can to their true form: 

  • Parallelogram
  • Midpoint of a Line Segment
  • Bisect an Angle
  • Center of a Triangle
  • Center of a Circle
  • Right Angle
  • Convergence Point of 3 Line Segments

Your speed and accuracy count. At the end of 21 questions you can see where you place among other site visitors who have played the “Eyeballing Game.” The game records your times and margin of error for each of your three tries.

This site is sponsored by an engineer who enjoys woodworking. You can see the rest of his site by clicking on the “Woodgears.ca” icon at the bottom of the game page. We have NOT reviewed that site, so parents, as always, should preview and supervise use.
